G4-GLS GPS_SD_Card Analysis
Good Morning!
Just want to share the results from a side project I'm doing.
1. I want to have a backup sana ng GPS-SD card ko
2. The unreasonably high cost of buying a new/orig one is NOT an option
3. Directly copying/duplicating the card, even per sector, is NOT working
4. No one, at least in this forum, seems to have made any good/provable result in backing-up the orig SD card. Let me know kung meron na po na validate na working...
Above forced me to do further study and got below inital result:
Looking at the SD card in windows explorer:
GenieTek/system/syscode.ini
You'll see soemthing similar below:
ETK6_PLUS,aabbccdd
*** I edited "aabbccdd" as I don't want publish my code.
The code "aabbccdd" seems to be a key that locks the software to the SD
There is this thing in the SD card called "CID".
This proved to be difficult to read directly and will need a specific reader/setup.
I was able to make a hardware reader and got from the my orig GPS-SD below:
ddccbbaa
See the pattern? Exact values in HEX, reversed
Now the theory is if I make a duplicate SD card and edit syscode.ini to reflect the correct CID of the duplicate SD, then it should work.
I'll be checking this theory later today.
Let me know guys if you are interested in the next results.
Maybe you want to help out further test this, should it work in my unit - let me know.
Sana ay makatulong kahit paano... :-)
